A possible name that comes to mind is Android Nutella. Though the site mentioned has been requesting for the names the next iteration of Android, I do not think those suggestions will make it to the final. After all, it is a business decision and there are many factors involved in the final decision. A few possible names could be
Nougat
Unlike Nutella, it is not a brand name. We may see the name becoming a reality.
Nesspresso
Google has been in association with Nestle before with the KitKat. A new association cannot be ruled out. But, will it be in tune with the nomenclature with desserts?
Nan Katai
Being an Indian, I would love to see that name. Though it is a rare possibility, it will indeed make the humble rural Indian dish a big name. With an Indian at the helm of affairs at Google, will it be a reality?
New York Cheesecake
This again is another name that has been doing the rounds. But it would be a big question whether Google will be ready for such huge name.
Besides, the Google Opinion Rewards App lists Napoleon, Nut Brittle, Nachos, Nori, Noodles, Nougat, and Neapolitan Ice Cream as options and wants you to vote for your favourite. Since Nachos, Nori, and Noodles are not desserts - we may need to drop them. Other names have a good chance of making it to the list.
Looking at the hints available over the different forums and some authority sites, it could either be Nutella or Nougat that may gain the final affirmation.
Live....and Let Live!
